^ from what i read this was good for 5hp...Now this is with the crappy oem filter but if you went with a good filter like a green one from
http://www.greenfilterusa.com/ ( better than K&N, higher quality materials ) I can guarantee you'd pick up probally a total of 10hp. I dont know if they have one out yet for the V but i'm sure they'll come out with one soon enough.
